摘要
三维地质建模技术对于矿山、石油等矿产资源的勘察、预测和开采具有十分重大的意义。本文阐述了利用Discover软件构建三维地质模型的关键技术及主要步骤流程,其中软件中构建三维模型的方法主要是基于面的建模方法(TIN、Grid和线框模型)和基于体的建模方法(Voxel)。针对地形表面、地层、矿体及断层等不同的地质对象以及不同的数据源,分别采用了不同建模方法及工具。并且以河北某矿区为例,利用该软件构建并展示了该区实际地质体的三维可视化模型,为矿产资源等领域的三维地质建模技术提供一种工具和应用范例。
3D geological modeling technology is of great significance to the surveying, forecasting and mining of mineral resources. This paper mainly describes the method and main steps of building 3D geological model using the Discover software, in which the main methods of the software structuring 3D geological model are those based on the surface （TIN, Grid and wireframe） and that based on the body （Voxel）. Different modeling methods are adopted according to different data sources and modeling objects such as strata, ore body, fault and so on. With a mining area in Hebei Province as an example, the researchers used Discover software to build and show the 3D visualization model of the actual geological body of that area, providing a new tool and paradigm for the 3D geological modeling technology of the mining resource area.
